Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 310-watt LED UFO high bay produces 45,000 lumens at 5000K for high-output indoor lighting layouts. Its round UFO form factor, hook mount, and 277-480V operation suit facilities using higher-voltage electrical systems.
The fixture is commonly considered for replacing 1000W or 1500W metal halide high bays where existing light levels, mounting locations, and electrical service support the conversion. Optional pendant and surface mounting provide additional installation configurations.
Core Performance and Output
The fixture delivers 45,000 lumens at 145 lumens per watt with an 80+ CRI. A standard 120-degree beam distribution provides broad downward coverage from the polycarbonate lens.
It operates on 277-480V, 50/60 Hz power with a 0.90 power factor and THD of 20% maximum. The 45,000-lumen output can be excessive at lower mounting heights, while higher mounting locations require layout review to maintain uniformity.
Adjustability and Control Options
0-10V dimming is provided for facilities using compatible dimming controls. An optional motion sensor is available for control strategies that require occupancy-based operation.
The fixture includes a 5-foot power cord and an 8-inch dimming cord. Control wiring and sensor requirements should be confirmed against the facility control design before installation.
Longevity and Reliability
This UFO high bay is rated for 50,000 L70 hours. The driver includes 4kV surge protection for added electrical protection.
The rated operating temperature range is -40F to 113F. Long-term performance depends on maintaining the fixture within this operating range and keeping the lens and mounting hardware in serviceable condition.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a black finish. The fixture measures 13.8 inches wide by 10.9 inches high and weighs 13 pounds.
An IP65 rating and IK10 impact rating support use in demanding indoor facility conditions. The polycarbonate lens protects the optical assembly while maintaining the 120-degree distribution.
Where This Product Fits Best
This high-output UFO high bay fits large indoor spaces requiring broad overhead illumination and 277-480V operation. The 45,000-lumen output is appropriate where fixture mounting locations and target light levels call for a high-output high bay.
- warehouse lighting
- distribution center lighting
- manufacturing facility lighting
- gymnasium lighting
- aircraft hangar lighting
- indoor sports facility lighting
The IP65 and IK10 ratings support facilities where fixture durability and enclosure protection are required. Final fixture placement should account for mounting height, existing electrical service, target light levels, and glare control.
Installation and Long-Term Use
Hook mounting is standard. Pendant and surface mounting are optional configurations. The fixture weight, mounting method, and mounting structure should be reviewed before installation.
Mounting height and fixture layout determine usable light levels and uniformity across the selected application. Higher output can reduce fixture count, but wider spacing can create lower light levels between fixtures.
How This Fixture Is Commonly Used
In warehouse lighting, distribution center lighting, and manufacturing facility lighting, fixtures are arranged in rows or grid patterns around building structure, work areas, and aisle layout. Mounting height is set according to the facility layout and required light levels.
For gymnasium lighting, aircraft hangar lighting, and indoor sports facility lighting, the broad 120-degree distribution is used for general overhead coverage. Fixture spacing varies with mounting height, target light levels, and the need to limit glare.
Safety, Certifications, and Warranty
UL listed. DLC Premium listed.
The fixture is IP65 rated, IK10 rated, and includes 4kV surge protection. Warranty coverage is 5 years.
